Re: Linux kernel exploit

   1. It ran on a one-time server which gets re-generated every time its
   restarted (which is everytime a testing session has finished)
   2. I did a *very* brief look in the code for shell code etc, and based on
   the noise already on the board, there wasn't any risk.
   3. Even if there was dodgy shell code in there, it still would have posed
   no risk, because the sandbox is re-generated every time (see comment 1)

No more troll feed for you!

wait wait wait.

you dont have time to read header notes, but do have time to run code you
dont really know what it does on your system?

can I send you some code? it's a linux 2.6.* 0day, remote root.

Sorry Dan, I did a very quick copy and paste job, without reading the
headers. I simply don't have time to read the code notes of every single
exploit released.

I would say that, if you are fed up with being inundated with emails, then
perhaps you should mark these notes very clearly in big red writing at
the top of the email like this, for those people who don't have much time
to read these notes ;)

Please don't inundate me with e-mail because none of you bothered to read
the exploit header.

The exploit so far has a 100% success rate on the systems it was designed
to work on.

I don't think this is rocket science.  If your distribution does not
compile Econet, then the exploit obviously won't be able to open an Econet
socket.  This includes Arch Linux, Gentoo, Fedora, Red Hat, CentOS,
Slackware, and more.  This doesn't mean you're not vulnerable, it just means
this particular exploit won't work.

If your distro doesn't export the relevant symbols (Debian), ditto above.

If your distro has patched the Econet vulnerabilities I used to trigger
this (Ubuntu), ditto above.

This was done on purpose, to avoid giving a weaponized exploit to people
who shouldn't have one.
